Hi guys,

I have a 98 3.2 tl. I was changing my O2 sensor yesterday and have a 7/8" o2 sensor socket but is seems to be not the best fit. My friend said that there is only one size socket for all 02 sensors and the 7/8" is the one. The 7/8" goes in but has some play....tried unscrewing sensor but will not budge. Did put some wd-40 on it. Now I'm afraid of rounding the sensor which will create a whole new can of worms.

Question. What is the metric size socket do I use for acura o2 sensor? Can I still get away with the 7/8" without rounding?

ya'll advice is appreciated.
